Anal sex with wife

Q: I want to know what is the kafara of doing anal sex with your wife when she is in her monthly periods . The husband claims that it was by mistake but the wife said that it was on purpose and this thing happened the second time and the first time both agreed that it was by mistake. I know there is a way in Islam to batch up with your wife if a person does toubah and promises not to do this thing again but what will be the kafarah?

Husband drinking wife's breast milk

Q:

1. Is it permissible for my husband to drink/swallow my milk intentionally and unintentionally. I am breastfeeding his son. Whilst making love to me he squeezes my breasts and sucks my nipples very hard and there is milk all round his mouth and I know he is also taking it inside.

2. Am I responsible to make food for my father in law when my husband calls me to bed to fulfil his needs and satisfy him? 

Having intimacy with one's wife while she is menstruating

Q: This is a general question but necessary all the time for those who are living abroad without their family. After long period (over 6 months). I am going for a short vacation to my home country for 5 days. During this 5 days, if my wife gets her menses, what do I need to do? Is it haram to get intimate with my wife or is it exempted, because i will not have another chance for several months thereafter.
